Attribute Macro overwrite_with

#[overwrite_with]

Similar to suppress_item, but will instead entirely replace the item this attribute is attached to with whatever item is specified in the attribute arguments.

Example

The following test will pass because invalid_rust() is not emitted and is instead replaced with hello_world(), which can then be referred to on subsequent lines:

#[overwrite_with {
    fn hello_world() -> usize {
        return 3;
    }
}]
fn invalid_rust() {
    return nonexistent_value;
}
assert_eq!(hello_world(), 3);
